Here, the coordinates of the vertices of the triangle in the image are (-8, 3), (-3, 6), and (-2, 1).
It is known that the coordinate (x, y) changes to (-x, y), if the figure is reflected over the y-axis.
So, the coordinates of the triangle will become (8,3), (3,6), and (2,1) after a reflection over the y-axis.
The image of the triangle is given below:
